I switched over several years ago, and shortly after even decided to use the free radeon driver only. Too bad that some more demanding/less Wine compatible games required an XP dual boot that I used only like once every few weeks or even months...

I've been playing around with the thought of a Xen emulated Windows with VGA passthru ever since, but I still lack the fitting mainboard for that... But one thing is sure: No Windows system after XP will touch my hardware, Xen will be first.
